  Calling all advanced Illustrator kids;

  Placed grayscale tiff. I'm determined to gradient fill in AI... obviously PS would be easiest.

  I thought there was some new way to gradient fill images but google is giving me nothing.

  I did figure out a nice little trick by using an opacity mask on the image with grad to zero, then duplicating ontop, flipping the opacity mask and filling image to 2nd color.

  works! but seems a little sketchy to send for screenprint seps.

  am i missing the obvious? punch in the face if you say Photoshop.

  Well, youre using a vector program to work on a bit map image, so...

  If its a black and white image (bitmap) you can just select it and change your fill to a gradient and it should work though.

  • no you can't directly apply gradients to placed grayscale or bitmap images.– inkpink1/2

    Ah, I thought I did it before, guess it mustve been "screen"– fresnobob2/2

  sorry just geeking out on AI really... mostly just wondering if there is a special trick out there.

  my duplicate opacity masks works ok, but something that didn't involve transparencies would be ideal.

  I don't have a picture of what you're trying to accomplish, but in CS4, you can have a gradient fade to alpha 0 (same as Flash)

  • yeah different– inkpink

  like this...

  

  • and yes pantone spot channels in photoshop, again just wondering if AI has caught up.– inkpink1/2

    actually this example is probably just cmyk, not spot, but whatevs– inkpink2/2

  trace the image to make it vector or at least to get a version of the shape you want to fill.

  but for the tshirt above it's a photoshop job.

  If you're using a raster image then transparencies are unavoidable.
  I'd have suggested opacity masks, which is pretty much what you'd be doing in Photoshop anyway. And Illustrator or not, you're still at the mercy of the raster image resolution.

  Anyway, have you tried creating seps from the opacity masked image?

  Just tried here via InDesign and it works a treat!

  it's just a photo which has turn into greyscale and then back to cmyk.
  then imported/placed in illustrator and gradient applied. with transparent "overlay" or something.

  make a giant shape with the gradient and copy-paste that into the photoshop file. then use the image (or invert image colour selection) as a mask.

  • ah yes!– inkpink

  yeah actually new image and the opacity masks are working pretty good... would be fine in cmyk.

  my technique:

  actually yes airey is right; an inverted image filled white and placed over the illustrator gradient would work for 2 color seps!

  thanks!

  • ahh, 2 colour with a gradient? you might need to sit down for this...– airey
